The condenser
a. is a heat exchanger
b. is a device where air passing over it cools the refriger- ant and causes it to change into a high-temperature liquid
c. transfers heat from the refrigerant to the air flowing
d. all of the above

option D

Explanation:

correct answer is option D

condenser  is also called as heat exchanger.

second statement is correct because when the hot air passes  through the condenser it converts it into cooler air and in this process change in high temperature takes place.

third statement is correct because it keeps on circulating air in the room and this process takes place so rigorously which maintains the room temperature.

as technology advances, new experiments often expose problems in accepted theories. c
